Synopsis of The Vans International Billionaire Julian Vance is a hyper-focused, notoriously paranoid tech billionaire weeks away from launching an autonomous shipping empire that will redefine global logistics. Driven by the ghost of his father’s financial ruin, Julian trusts no one and relies strictly on cold, hard logic. But when a catastrophic routing error threatens to tank his company’s imminent IPO, he leaves a chaotic, failed algorithm scrawled across his penthouse office glass wall in a fit of midnight rage.
